So, is the promise of a diverse fediverse a pipe-dream? Are the platforms up to the challenge of integrating with all the others? Or are people happy with a single UI?
I think it's "no" to all three. Which means something is being missed here (this is new after all).
A similar conversation happened recently over on #bluesky. It's a UI issue but at a system level and I'm not sure anyone has good solutions or is even thinking seriously about it.
